Details

The stuff of legends, the Moog transistor ladder filter changed the
face of the musical landscape forever. The MiniMod VCF is a faithful
replica of the 24db/octave low pass filter used in the early Model D
synthesiser.

There is a three channel input mixer and a nice large
filter cutoff control, along with “1/3” and “2/3” CV inputs to emulate
the action of the original VCF keyboard switches, apply 1v/oct to
either of these inputs and the VCF keyboard tracking will be the same
as the original with Keyboard 1 (1/3) or 2 (2/3) engaged, or use the
1v/oct input to emulate both switches selected. There is a variable
Exponential CV input which is about 30% more sensitive than the 1v/oct
input, this allows some nice over modulation effects.

We have added Voltage Controlled Resonance (Emphasis)
in addition to manual Emphasis control. This uses a vactrol as the
control element. The fast vactrol used allows modulation speeds up into
the audio range. The filter will of course self resonate and act as a
sine wave oscillator too.

There is also an overdrive facility which can be selected
with an onboard jumper. This allows the input to the filter core to be
substantially overdriven, great for adding a bit of extra dirt to the
sound.
